The chemical "8-methoxycarbonyloctyl 3,4,6-tri-O-acetyl-2-O-(2,3,4,6-tetra-O-benzyl-α-D-glucopyranosyl)-α-D-glucopyranoside" is a complex organic compound with a molecular formula of C47H68O15. It is a glycoside derivative, consisting of a glucopyranosyl unit attached to an octyl chain through a methoxycarbonyl group. The octyl chain is further modified with three acetyl groups at the 3, 4, and 6 positions, while the glucopyranosyl unit is protected with four benzyl groups at the 2, 3, 4, and 6 positions. 8-methoxycarbonyloctyl 3,4,6-tri-O-acetyl-2-O-(2,3,4,6-tetra-O-benzyl-α-D-glucopyranosyl)-α-D-glucopyranoside is typically used in the synthesis of complex carbohydrates and glycoconjugates, and its structure provides a stable and protected form for further chemical modifications.
The CAS Registry Mumber 100644-77-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,6,4 and 4 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 100644-77: (8*1)+(7*0)+(6*0)+(5*6)+(4*4)+(3*4)+(2*7)+(1*7)=87 87 % 10 = 7 So 100644-77-7 is a valid CAS Registry Number.
