Check Digit Verification of cas no

The CAS Registry Mumber 1381875-01-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,1,8,7 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1381875-01:
(9*1)+(8*3)+(7*8)+(6*1)+(5*8)+(4*7)+(3*5)+(2*0)+(1*1)=179
179 % 10 = 9
So 1381875-01-9 is a valid CAS Registry Number.

Preparation of C 2-symmetric allenes by palladium-catalyzed double-nucleophilic substitution on 3-bromopenta-2,4-dienyl acetate

Ogasawara, Masamichi,Suzuki, Mayuka,Takahashi, Tamotsu

, p. 5406 - 5410 (2012)

Easily accessible 3-bromopenta-2,4-dienyl acetate was applied to the palladium-catalyzed reaction with soft nucleophiles. The reaction proceeded through the stepwise 2-fold nucleophilic substitution via formal S N2′ and SN2 processes
