Check Digit Verification of cas no
The CAS Registry Mumber 140365-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,3,6 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 140365-33:
(8*1)+(7*4)+(6*0)+(5*3)+(4*6)+(3*5)+(2*3)+(1*3)=99
99 % 10 = 9
So 140365-33-9 is a valid CAS Registry Number.

SYNTHESIS OF SECOISOQUINOLINE ALKALOIDS. TOTAL SYNTHESIS OF SAXOGUATTINE
Rozwadowska, Maria D.,Chrzanowska, Maria
, p. 1287 - 1290 (2007/10/02)
A total synthesis of saxoguattine (1) was performed by using aldehyde 4 and isovanillin 1,3-propylene dithioacetal (5) as building blocks.The formation of C-C bond between them was the key step in the synthesis and involved addition of dilithio salt of di
