Check Digit Verification of cas no

The CAS Registry Mumber 210818-37-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,0,8,1 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 210818-37:
(8*2)+(7*1)+(6*0)+(5*8)+(4*1)+(3*8)+(2*3)+(1*7)=104
104 % 10 = 4
So 210818-37-4 is a valid CAS Registry Number.

Formation of a pentacoordinate 1,2-oxastannetanide by novel base-induced rearrangement of a bis(β-hydroxyalkyl)stannane

Naganuma, Kenji,Kawashima, Takayuki,Okazaki, Renji

, p. 513 - 516 (1997)

Treatment of a bis(β-hydroxyalkyl)diphenylstannane with potassium hydride in THF in the presence of 18-crown-6 gave the corresponding pentacoordinate t-alkoxy-1,2-oxastannetanide as stable crystals instead of a hexacoordinate stannate with two oxetane rings. This compound is considered to be formed by novel tin-1,3-migration reaction from carbon to oxygen reaction involving the formation of an oxetane ring and the subsequent tin-carbon bond cleavage.
